Entire coastline is lovely but starting at station 4 gives you the most scenic portion without weekend family chaos.

Bike rental options available throughout the park, path toward Changi is beautifully maintained with regular rest stops. Early morning (before 9am) or late afternoon (after 4pm) avoids the rush. Proper washrooms every few kilometres, fresh coconut water stalls throughout. Sea breeze makes it comfortable even in Singapore heat. The stretch offers wonderful views of container ships and occasional dolphins if you're lucky.
